    This video deserves an Oscar for effort put in its creating ! All those circuits designed as to look as a schematic diagram, the graphics moving and changing color, all the details explained, the oscilloscope graphics... Everything is so good arranged and easy to understand, put in such an order. I`m not surprised it`s done by a German. And he is very good in English speaking as well for a German. Great respect to the person spent probably close to a week to develop all the prototypes, cut open the housings of the servos so they could be observed and then filmed this video (or I better say movie according to its length) ! And on top of all that it has detailed Table of content in the description... Unbelievable attention to the detail !
    Thank you, HomoFaciens, and great luck in your business !
    I hope more viewers will appreciate what you`ve done!

      Д. Станоев Thanks! Its people like you I am doing all this work for. In total it was more than one week. It took almost a day to record the audio track because I usually need more than one try for a section in the English version or else it would sound even more like German English ;) Share the link to this video and perhaps that of my homepage, too: www.homofaciens.de/technics-base-circuits-servos_en_navion.htm

    This is excellent.

      You should give some more information about your creations to make other youTubers understand what you have done. RUclips is more than just presenting own stuff it's spreading knowledge. Maybe an audio track with your comments makes your videos more interesting. What kind of motor are you using? It is running very smooth.

    hello.I have a couple of questions if you don't mind :D that is an integrated circuit or a microcontroller?I need a servo for an RC car for turning left or right and I have no ideea how to connect the servo to the receiver (4 channels).The transmitter haves obviously 4 signal outputs with basically push-to-ON switches.Can I use on one channel insted of a switch a pottentiometer like the one you used on the video and directly connect the signal orange cable of the servo to one afferent channel output of the receiver?I need this for my bachelor degree.if you have any indication that would be greeat and I would be very thankfull.

    Thank you for the answer. I have built a big paddleboat model whith a 12V 80W motor.A PWM unit controls the speed whith a potentiometer. The servo turns 90degrees but the potentiometer turns 270 so I cant fix them together so I have done some kind of mecanikel gear.Would have been better al electronic but I think it have to stay this way

    • @HomoFaciens
      @HomoFaciens  9 лет назад

      Chris De Berg I suggest to keep that mechanical solution. Adding an electronic circuit to the existing control loop might worsen the result.

    Have u any idea how to transform a PWM signal from a RC reciver to a PWM signal that controls a DC motor?

    • @HomoFaciens
      @HomoFaciens  9 лет назад

      Chris De Berg The really simple way is buying a RC motor controller ;)
      Using an Arduino is simple if you are skilled in using microcontrollers. Analog circuits are tricky to implement. You can try to convert the PWM signal into a DC voltage as demonstrated in the video and reconvert that DC signal into a PWM signal through an astable multivibrator if you'd like to learn how it works. It will be a long way to build a good quality circuit that way...

    Hello, i it possible to modify servo in a such way, so that value from the potentiometer is read by the arduino as well? So that micro controller can detect situations where servo is commanded to assume position but it did not (perhaps some mechanical obstruction)

    • @HomoFaciens
      @HomoFaciens  8 лет назад

      +Davorin Ruševljan
      Yes, you can read the servo position through the wiper and an analog input of the Arduino, assuming you know how to do the coding. Don't forget to limit the input voltage of the analog input (in case your servo operates with more than 5V).

      They are usually connected close to the MOSFETs, because these are the devices to get protected by the freewheeling diodes.

      Inserting a capacitor in the H bridge won't succeed. I will soon (probably in some weeks) publish a video about microcontrollers, demonstrating how to build digital servos. I guess something like that would be the best solution to your problem.

    Half the arrows of your FET's at the 11 minute mark are pointing in the wrong direction (Half should be n-channel and half p-channel). However at the 15 and 28.50 minute mark you can see the correct schematic with the correct FET's.

    I learned a lot from your video. Thanks for your enormous effort.
    I have one question. Can H-Bridge be build using combination of NPN and PNP transistors instead of IRF9Z34N and IRLZ24N?

    • @HomoFaciens
      @HomoFaciens  10 лет назад +1

      You're welcome!
      Yes, you can also compose an H-Brige of NPN and PNP transistors as demonstrated in my video about that circuits:
      Working priciple of H bridges
      and written on my project page:
      www.homofaciens.de/technics-base-circuits-h-bridge_en_navion.htm
      Bipolar transistors are more tricky to handle, since the base current has to be considered, which is very high for high power types. This type of H-Brige can't be driven directly by a low power op-amp as used in the video. You have to insert an additional amplifying stage between the op-amp and the power H-bridge.
